Published How the ketogenic diet improves healthspan and memory in aging mice



The ketogenic diet has its fanatics and detractors among dieters, but either way, the diet has a scientifically documented impact on memory in mice. While uncovering how the high fat, low carbohydrate diet boosts memory in older mice, scientists identified a new molecular signaling pathway that improves synapse function and helps explain the diet's benefit on brain health and aging.
Published Custom-made molecules designed to be invisible while absorbing near-infrared light



Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light. This compound demonstrates the first systematic approach to producing such materials and have applications in advanced electronics. This compound also shows semiconducting properties.
Published A high-fat diet may fuel anxiety



New research shows when animals are fed a diet high in saturated fat for nine weeks, their gut bacteria change in ways that influence brain chemicals and fuel anxiety.
Published Wear it, then recycle: Designers make dissolvable textiles from gelatin



Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.
Published Previously uncharacterized parasite uncovered in fish worldwide



Using genome reconstruction, scientists unveiled a once 'invisible' fish parasite present in many marine fish world-wide that belongs to the apicomplexans, one of the most important groups of parasites at a clinical level. However, it had gone unnoticed in previous studies. The parasite is geographically and taxonomically widespread in fish species around the planet, with implications for commercial fishing and oceanic food webs.
Published Molecular sponge for the electronics of the future



An international research team has succeeded in developing a new type of material in the rather young research field of covalent organic frameworks. The new two-dimensional polymer is characterized by the fact that its properties can be controlled in a targeted and reversible manner. This has brought the researchers a step closer to the goal of realizing switchable quantum states.
Published Breakthrough approach enables bidirectional BCI functionality



Brain-computer interfaces or BCIs hold immense potential for individuals with a wide range of neurological conditions, but the road to implementation is long and nuanced for both the invasive and noninvasive versions of the technology. Scientists have now successfully integrated a novel focused ultrasound stimulation to realize bidirectional BCI that both encodes and decodes brain waves using machine learning in a study with 25 human subjects. This work opens up a new avenue to significantly enhance not only the signal quality, but also, overall nonivasive BCI performance by stimulating targeted neural circuits.
Published Research into structures of ape hearts provide insight into human evolution



Researchers have discovered new insights into the human heart's structure, revealing its evolutionary history. This study enhances understanding of heart development and its implications for treating heart disease.
Published Some CRISPR screens may be missing cancer drug targets



CRISPR/Cas9 gene editing has made possible a multitude of biomedical experiments including studies that systematically turn off genes in cancer cells to look for ones that the cancer cells heavily depend on to survive and grow. These genes, or 'cancer dependencies,' are often promising drug targets. But new research shows that many of these CRISPR screening experiments rely on components, called CRISPR/Cas9 guides, that do not perform equally well in cells from people of all ancestries, which can cause CRISPR screens to miss cancer dependencies.
Published When bacteria are buckling



Filamentous cyanobacteria buckle at a certain length when they encounter an obstacle. The results provide an important basis for the use of cyanobacteria in modern biotechnology.
Published Nano-immunotherapy developed to improve lung cancer treatment



Researchers have developed a new nanomedicine therapy that delivers anticancer drugs to lung cancer cells and enhances the immune system's ability to fight cancer. The team showed promising results for the new therapy in cancer cells in the lab and in mouse lung tumor models, with potential applications for improving care and outcomes for patients with tumors that have failed to respond to traditional immunotherapy.
Published Vitamin B6: New compound delays degradation



A low vitamin B6 level has negative effects on brain performance. A research team has now found a way to delay the degradation of the vitamin.
Published Strengthener for graphene



Layers of carbon atoms in a honeycomb array are a true supermaterial: their unusually high conductivity and favorable mechanical properties could further the development of bendable electronics, new batteries, and innovative composite materials for aeronautics and space flight. However, the development of elastic and tough films remains a challenge. A research team has now introduced a method to overcome this hurdle: they linked graphene nanolayers via 'extendable' bridging structures.
Published The genetic 'switches' of bone growth



In mammals, only 3% of the genome consists of coding genes which, when transcribed into proteins, ensure the biological functions of the organism and the in-utero development of future individuals. But genes do not function alone. They are controlled by other sequences in the genome, called enhancers, which, like switches, activate or deactivate them as required. A team has now identified and located 2700 enhancers -- among millions of non-coding genetic sequences -- that precisely regulate the genes responsible for bone growth. This discovery sheds light on one of the major factors influencing the size of individuals in adulthood, and explains why their failure could be the cause of certain bone malformations.
Published Self-assembling and disassembling swarm molecular robots via DNA molecular controller



Researchers have succeeded in developing a DNA-based molecular controller. Crucially, this controller enables the autonomous assembly and disassembly of molecular robots, as opposed to manually directing it.
Published Study on architecture of heart offers new understanding of human evolution



An international research team has uncovered a new insight into human evolution by comparing humans' hearts with those of other great apes.
Published Fasting primes the immune system's natural killer cells to better fight cancer, new study in mice finds



A team of researchers has shown for the first time that fasting can reprogram the metabolism of natural killer cells, helping them to survive in the harsh environment in and around tumors, while also improving their cancer-fighting ability.
Published Infectious H5N1 influenza virus in raw milk rapidly declines with heat treatment



The amount of infectious H5N1 influenza viruses in raw milk rapidly declined with heat treatment in laboratory research. However, small, detectable amounts of infectious virus remained in raw milk samples with high virus levels when treated at 72 degrees Celsius (161.6 degrees Fahrenheit) for 15 seconds -- one of the standard pasteurization methods used by the dairy industry. The authors of the study stress, however, that their findings reflect experimental conditions in a laboratory setting and are not identical to large-scale industrial pasteurization processes for raw milk.
Published Novel insights into fluorescent 'dark states' illuminate ways forward for improved imaging



Scientists address decades-long problem in the field of single-molecule fluorescence resonance energy transfer, paving the way for more accurate experiments.
Published Making ferromagnets ready for ultra-fast communication and computation technology



Researchers have made a significant breakthrough in how to enable and exploit ultra-fast spin behavior in ferromagnets. The research paves the way for ultra-high frequency applications.
